Permeability of placing joint of cement mortar during casting was measured for the specimens placed at various interval times at the combined environmental conditions of temperature and relative humidity. Temperature directly affects the permeability of them, and the rise of it increases permeability. However, a slight influence observed for humidity. Pore structure of placing joint zone was furthermore investigated by the Ga intrusion technique recently developed. The pore structure becomes coarse and finally a clear porous line appeared along placing joint, according to particularly rise of temperature as well as delay of the jointing time. Finally, the relation between permeability and proctor penetration resistance was discussed.
